hope this will help u

Answer 2

let a right angled triangle ABC right angled at B then base BC = 1.2m and hypotenuse AC =3.7m
by Pythagoras theorem,
$ac {}^{2} = ab {}^{2} + bc {}^{2}$
ab^2 = (3.7)^2- (1.2)^2
= 13.69- 1.44
= 12.25
ab = 3.5m (taking root)

now area triangle ABC = 1/2 × BC × AB
= 1/2 × 1.2 × 3.5
= 0.6 × 3.5
= 2.10m^2 ans


mark me as a brainliest if my ans is right
